Yeah and some buyer requests are actually spams with there own link.
One thing to add: if a scam or spam reaches your inbox, you better first respond asap in order to not ruin your response time and then report their message to Fiverr (in inbox). I have had a bad experience once with such a message that was not answered that is why I suggest so. Also Fiverr changes the rules from time to time. So, just in case, better respond asap by saying e.g. “Hi, this is against the TOS, thanks for your offer but no!” or something similar and then report.
